REVOLVING TABLE FOR TILE-MILLS.

SPECIFICATION forming part of Letters Patent No. 267,760, dated November 21, 1882.

Application filed July 27, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOHN S. SMITH, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements'in Revolving Tables for Tile-Mills, of which the following is a specification, reference being had therein to the accompanying drawings. p

This invention relates to improvements in the process and the mechanism for removing tiles (after they have been formed and cut) in such manner that they shall not be damaged nor have their shape marred.

It consists partly in a method of removing tiles from, the forming and cutting mechanism in such manner that the tiles shall be supported both on theinside and the outside to prevent marring and misshaping, and so change the position of the tile that it can be removed from the machine without danger.

It consists, further, in a series of revolving tables mounted upon the axis, one table being presented at a time to receive a tile. After a tile has been received and cut off theproper frame on the line y y, Fig. 2. Figs. 5, 6. and.

7 show the interior supporting-drum. Fig. 8

is a view of the spring-catch and one of the troughs while in engagement therewith.

The machine or the parts thereof essentially intended to carry out my invention may be combined with a tile-mill of any of the wellknown forms, or with one of any preferred It may be mounted upon a frame- I work of any suitable character more or less different from that shown.

In the drawings I have shown a main supporting-frame constructed of the uprights or legs A A, the sills or longitudinal pieces B B,

manner that the height of the machine can be adjusted upon them. Upon this frame is mounted another adapted to be moved up and down to a limited extent, thelatter frame consis-ting of the side pieces, A, and the crosspieces 13 B. These two frames are connected by means of links WM? and curved connecting arm or bar N. The said bar is slotted, as at n, and pivoted at a to the upper frame, there being a set-screw, a in the slot a, by which the frame A B may be supported in any desired position.

N is an adjustable handle carried by the frame N, and pivoted at n to the frame B. 6 By means of this the adjustment can be readily and instantly made. i

A sliding frame is supported upon the frame A B and arranged to carry the revolving tile-support. It is constructed of side bars, A and an end bar, B and is mounted upon the frame A B, preferably by means of rollers A which permit it to easily slide upon the lower frame. Upon this frame is mounted a transverse shaft, D. To the shaft are secured four 7 troughs, E E E E, or recessed plates, they being situated at substantially ninety degrees apart.

At one of the frames A A there is arranged a cut-off mechanism. Preferably it consists of an arched plate, F, provided with a slot, f, and the wire-carrying arm G. The wire 9 is so arranged that as the arm or handle G is caused totraverse the arched plate F the wire cuts the tube of "clay and forms a tile of the proper 8 5 length. In the construction shown in the drawings the wire has its lower end attached to an eye, 9, which is connected by a hinge with the spring 9 the spring being arranged to yield somewhat, so that when the wire comes in contact with small stones or other hard substances in the clay the wire may yield sufficiently to prevent a marring of the tile. At the upper end the wire is attached to an eye or hook, a at the lower end of a threaded hook, 7L3. This 9 5 threaded rod is held in the carrying-arm, G,

which is provided with a longitudinal aperture to receive it.

It is a thumb-nut engaging by thread-counection with the rod b and by means of it the '100 tension of the wire may be delicately adjusted.

The wire-carrying arm G is cast with or secured to a curved plate, G, which conforms as accurately as possible to the outer face of the arched plate F, it being formed with lugs or ears h which are turned down and under the plate F to provide a clamp to hold the plate F in place. The inner end of the wire-carrying rod k moves back and forth in the slotf. However, I do not limit myself to this exact form of cutter, for some of the features of my machine may be embodied without its being restricted to this form of cutter, though I find that my form possesses advantages when combined in the way shown with the parts to behereinafter described.

Before the tile is out the frame A B is moved up into proper position relatively to the tilemill. As the tile issues from the mill it is deposited upon the troughor curved plate E, that has been brought up to receive it. It moves along said trough or plate until it strikes against a removable plate, I, that is placed against the back of the trough E, which is in a vertical position. After it strikes against the vertical plate I the upper frame moves relatively to the lower frame, and the tile is then out. As soon as cut the shaft D is revolved on e-quarter of a revolution,which brings the tile from the horizontal position into the vertical position,it resting, after being brought into the vertical position, upon the removable plate I. It can be readily taken away while standing vertically by removing the plate I, which has now been brought into a horizontal position. Throwing the tile into the vertical position, and with it the trough with which it is in contact, brings the next trough or curved plate into a horizontal position proper to receive the next tile. Before the next tile has been entirely received upon the trough the upper frame should be removed back into its original position relative to the tile-mill.

It will be seen that the four troughs E E E E form a revolving table, and that each part of the table in turn receives a tile in a horizontal position and raises it on end before itis removed from the table.

With the revolving table I combine a springcatch, which operates to stop the table in a proper position to receive the tile, and which can be withdrawn to permit the next movement of the table. I have shown in the drawings one form of spring-catch, though others will readily suggest themselves, adapted to perform substantially the same operations. The one shown consists of the laterally-moving piece J, which permits the plates to come successively up to a horizontal position, and a lateral part, J, which prevents them from rising above said position until it (said part J) has been intentionally withdrawn by the operator. The part J of the stop prevents the plates frommoving downward while they are receiving the tiles. Both of these parts J J may be made in one piece of metal, as will be readily understood. For some purposes, however, I prefer to construct them separately, as

arranged I mount the parts thereof in a bracket-piece, K, carried by the frame of the revolving table.

To prevent the plates or troughs from being worn away by the action of the spring-catch, I provide each of them with wearing-plates is It, so situated that when the catch engages with the plates the contact shall be received by them.

With the revolving table, in order to get the best results, I combine a stationary trough or table, L, so situated as to first receive the tile as it issues from the mill and before it is out. It is secured in position by means of angleirons l l, which are slotted, as at l, to receive the clamping-screws 1 whereby the trough L r is secured to the frame. If vertical adjustment .is necessary, it is permitted by the slots Z.

As the tile issues from the mill I insert into the end thereof a detachable cylinder or drum, M, of suitable length, the external diameter of which is substantially the same as the internal diameter of the pipe or tube of clay. I leave it there until the tile has been turned upon end, after which I draw the drum through the tile from the end into which it was inserted to the other. The objects of this are, first, to keep the end of the tile from flattening as it runs along the trough and, secondly, to form a perfect cylinder of clay, and remove or clean away the ragged edges that are generally left by the wire on the inside of the tile, in this way 0bviating the tedious process of trimming or finishing with a knife, which is now necessary. The revolving table is adjusted in the rolling frame which carries it, the adjustment being effected by means of slots at d in the side pieces of the frame and the shaft D, which can be moved in said slots and secured in different positions by means of clamping-nuts d d.

The drum or cylinder M is preferably constructed as shownthat is, with heads m m and slats m fastened thereto. In order to draw it easily through the tile, a handle may be attached to it, as shown in Figs. 4 and 5; or a separate handle may be used in withdrawing it, as shown in Fig. 7; but I do not limit myself to the use of such handles, as the purposes of the drum can be accomplished without such a device.

WVhat I claim is- I l. The combination, with the revolving table of a tile-mill having the plates or troughs E E,

of the frame-work which holds said table, a

separate main frame, and rollers interposed betweenthe two, whereby as the revolving table is turned upon its axis'it may be moved toward or from the tile-mill, substantially as set forth.

2. The combination, with the revolving table of a tile-mill having the plates or troughs E, of a spring-catch provided with a lower rounded or beveled edge, which permits each table in turn to pass upward, and provided with a flat stopping-edge above the rounded or beveled edge,which prevents the tables from moving downward, substantially as set forth.

3. The herein-described process of forming tiles of a tubular or concave form, it consisting in delivering a tube of clay from the tilemill to a movable support, placing in the outer end of said tube a shaping and supporting device, then cutting off the tile at the required point, then lifting the tile into such position that the axis thereof shall be vertical, substantially as set forth.

4. The herein-described process of forming tiles of a tubular or concave form, it consisting in first supporting a tube of .clay from a tile-mill, inserting into the outer end of said tube a cylinder or drum,receiving said tube of clay upon a horizontal support, then cutting off saidtile from said tube at the required it is received from the mill, and to be drawn through it from the other end, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
